F31_DMUL

Multiplies the 32-bit data or 32-bit equivalent constant specified by s1 and the one specified by s2 if the trigger EN is in the ON-state. The result is stored in d[0], d[1] (64-bit area). All 32-bit values are treated as double integer values.

Parameters

Input

s1 (DWORD, DINT, UDINT, DATE, TOD, DT)

Multiplicand

s2 (DWORD, DINT, UDINT, DATE, TOD, DT)

Multiplier

Output

d ARRAY[0..1] OF (DWORD, DINT, UDINT, DATE, TOD, DT)

Result

Remarks

• If the required data type is supported, we recommend using the IEC instruction MUL.

• The variables s1, s2 and d have to be of the same data type.
